Help! Wireless Not Connecting

[mysticsniper]

Within the past 24 hours. I noticed that my wireless connection had dropped. The router was turned on downstairs, but I was unable to connect. I typed in the SSID and the passcode, but it kept saying "unable to connect".

I then took the computer downstairs and connected it to the router via the cat5 cable. I have since been able to connect to the internet and when I click on the wireless device. It tells me I am connected. But as soon as I remove the Cat5 cable, I lose my connection.

So far, I have changed the SSID, and the encryption and the passcode. I have even updated all the drivers and even been into the TCPIP setting, to make sure it obtains an IP address automatically But I am quite stumped now

I am using the following hardware

Netgear DG834N Router
Netgear WPN311 Wireless Card

Reboot the router ?

It could be that a neighbour nearby is using the same wireless channel as you and is conflicting with your wireless connection. When you look for SSID's does it come up with someone elses also and what is the signal strength ?

If you have say your channel set as 1 try and move it to the other end of the scale say 11.

Yeah have rebooted several times. I am on channel 6 at the moment, will change to a different one and see what happens. My SSID is hidden amd not being broadcast, so I have to input that manually.
